Hi Sumit and thanks so much for your answer.
I already tried to reinstall the VPN program.
Some colleagues of mine have installed the same update on same hardware and OS and the VPN works correctly, so I wouldn't think it's a VPN certification problem.
I also sent a feedback on the hub and it should have some diagnostic data attached with it, I don't know if you can check it. Here's the link:
Maybe there's some further detail useful to find out the problem.
Waiting for your answer.
Thanks again.
Nick
